[0002] Polyethylene composite pipes are made by simultaneously extruding two different densities of polyethylene resin using two separate extruders, and then extruding the molten material into a single mold to form a composite pipe. This type of composite pipe can be made from various plastics through extrusion. Pipes formed from high-density polyethylene and low-density polyethylene combine the characteristics of both raw materials, resulting in better pressure resistance and corrosion resistance than ordinary polyethylene pipes. In industrial and mining enterprises, these composite pipes can replace steel pipes for transporting corrosive media such as oil and gas, or for mine ventilation. Currently, polyethylene composite pipes cannot be thickness-tested at different locations; therefore, we have developed an online thickness testing device for polyethylene composite pipes.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an online thickness detection device for polyethylene composite pipes, including a detection frame 1 and a propulsion mechanism 4. A rotatable rotating mechanism 2 is provided on the upper inner wall of the detection frame 1. The rotating mechanism 2 includes a turntable 201, a connecting frame 202, and an insertion rod 203. The turntable 201 is located on one side of the outer wall of the detection frame 1. The turntable 201 is movably connected to the detection frame 1 through the connecting frame 202. The turntable 201 is fixedly connected to the detection frame 1 through the insertion rod 203. Rotating the turntable 201 causes the connecting frame 202 to rotate automatically, thereby adjusting the angle of the thickness detection mechanism 3. This allows for thickness detection at different positions on the inner wall of the polyethylene composite pipe. Inserting the insertion rod 203 into the inner wall of the detection frame 1 allows for positioning of the turntable 201.

[0021] A thickness detection mechanism 3 is fixedly installed on one side of the outer wall of the rotating mechanism 2. The thickness detection mechanism 3 includes an arc-shaped block 301, a fixed block 302, a detection ruler 303, a positioning block 304, a threaded rod 305, and a contact block 306. The arc-shaped block 301 is welded to one side of the outer wall of the rotating mechanism 2. The arc-shaped block 301 is fixedly connected to the detection ruler 303 through the fixed block 302. The positioning block 304 is fixedly installed on the lower part of the outer wall of the detection ruler 303. The threaded rod 305 is fixedly installed on one side of the inner wall of the positioning block 304. The contact block 306 is movably connected to the upper part of the outer wall of the threaded rod 305. The thickness detection mechanism 3 rotates the threaded rod 305. 05. This allows the positioning block 304 to move within its inner wall, thus moving the contact block 306 up and down. This enables the detection of the inner wall thickness of the polyethylene composite pipe. The scale on the measuring ruler 303 of the contact block 306 directly measures the thickness of the polyethylene composite pipe. The threaded rod 305 is threadedly connected to the positioning block 304. The contact block 306 has an arc-shaped structure, which allows for stable adjustment of its up and down position, ensuring it fits the upper and lower positions of the polyethylene composite pipe. This allows for direct display of the thickness of the polyethylene composite pipe.

[0022] The propulsion mechanism 4 is fixedly installed on the lower side of the inner wall of the rotating mechanism 2. The propulsion mechanism 4 includes a hydraulic cylinder 401, a hydraulic rod 402, a fixed disc 403, and an insert plate 404. The hydraulic cylinder 401 is fixedly installed on the lower side of the outer wall of the connecting frame 202. The output end of the hydraulic cylinder 401 is provided with a hydraulic rod 402. A fixed disc 403 of matching size is provided on one side of the outer wall of the hydraulic rod 402. Insert plates 404 are welded and installed on both sides of the inner wall of the fixed disc 403. When a polyethylene composite pipe is placed on the fixed disc 403, the insert plate 404 can... The polyethylene composite pipe is positioned to abut against the hydraulic cylinder 401, thus stabilizing its placement. The hydraulic cylinder 401 is powered on, causing the fixed disc 403 mounted on the outer wall of the hydraulic rod 402 to move. This allows the polyethylene composite pipe to be positioned near the lower part of the cylinder 301. The insert plates 404 are trapezoidal in shape and evenly distributed on the fixed disc 403. The insert plates 404 on both sides abut against the polyethylene composite pipe, thus stabilizing its placement.

[0023] Working principle: First, place the device in the designated position, and place the polyethylene composite pipe on the fixed disc 403. The insert plate 404 can abut against the position of the polyethylene composite pipe, thereby stabilizing its placement. Turn on the power to the hydraulic cylinder 401, causing it to move the fixed disc 403 mounted on the outer wall of the hydraulic rod 402. This allows the polyethylene composite pipe to move closer to the lower position of the arc-shaped block 301. Rotate the threaded rod 305 to move it within the inner wall of the positioning block 304, which in turn moves the abutment block 306 up and down. The thickness of the inner wall of a polyethylene composite pipe can be detected. The scale on the measuring ruler 303 of the contact block 306 can directly detect the thickness of the polyethylene composite pipe. Rotating the turntable 201 causes the connecting frame 202 to rotate automatically, which can adjust the angle of the thickness detection mechanism 3, thereby enabling thickness detection at different positions of the inner wall of the polyethylene composite pipe. Inserting the insertion rod 203 into the inner wall of the measuring frame 1 can position the turntable 201. This completes the operation process of an online thickness detection device for polyethylene composite pipes.
